Title: Intake device for engine
Inventor: IMAMURA NAOKI
IPC: F02B27/02
Filed: 1988-01-30
Abstract: PURPOSE:To achieve good resonant supercharge effect by arranging a normal close gate valve, opening operation thereof is interlocked with closing operation of a throttle valve, in a path communicated with the downstream of the throttle valve and having a pressure inverting section. CONSTITUTION:In the low load area of an engine 1 where the opening of a throttle valve 11 is small, a communication path 15 is opened through opening operation of a gate valve 16 interlocked with closing operation of the throttle valve 11. Consequently, negative pressure wave of intake air produced through the intake stroke of each cylinder passes through the communication path 15 without being damped through the throttle valve 11 having small opening. The negative pressure wave of intake air fed from each cylinder on one cylinder group collides, in the way of the communication path 15, with that fed from each cylinder in the other group and converted into a positive pressure wave which returns to the downstream side and functions onto each cylinder. Consequently, good resonant supercharge effect can be achieved and the engine 1 can exhibit a stable output characteristic over a wide region.

Title: Color burst processing circuit of video disc player
Inventor: FUKUI TSUTOMU
IPC: H04N9/89
Filed: 1983-02-10
Abstract: PURPOSE:To remarkably improve the accuracy of phase detection by a color burst signal by providing a peak hold circuit comprising mainly diodes and obtaining a pulse appearing for only the color burst signal period. CONSTITUTION:A DC component is eliminated from a color burst signal obtained from a BPF1 by a capacitor C1 in a peak hold circuit 2 and held in a capacitor C2 via a diode D. This voltage is applied to a voltage comparator 3 via a voltage follower V. Thus, when a signal waveform at a check point (a) has a peak value, the peak value of the signal waveform at a check point (b) is decreased by the forward voltage drop of the diode D. Thus, the signal waveform at the check point (c) is a waveform where only the level of the color burst signal exceeding the level at the point (b) appears and no noise component is outputted. Thus, the point of time of leading and trailing is coincident with the period of the color burst signal in the signal waveform at a check point (d) and the pulse is suitable as a sample-hold pulse.

Title: Slip controller for vehicle
Inventor: NAKAJIMA HITOSHI
IPC: B60T8/175
Filed: 1988-01-31
Abstract: PURPOSE:To surely enable starting under self control in a device where slipping of drive wheels against a road surface is restrained by controlling torque to the drive wheel by prohibiting slip control upon starting. CONSTITUTION:Generation of torque is controlled by controlling the opening of a throttle valve 13 arranged at an intake path 12 of an engine 6. The throttle valve 13 is controlled at its opening by controlling operation of a throttle actuator 14 controlled by a control unit U. Excessive slipping on a road surface is prevented by controlling generation of torque, i.e. torque to drive wheels. In such a device, when starting of a vehicle is detected by means of detection signals from a vehicle speed sensor 64, acceleration opening sensor 67 and the like, the aforesaid slip control is prohibited, and starting is performed by driver's self control.

CONSTITUTION:By performing optical expansion, the reading range of an original D in a main scan direction is narrowed, and no designation levers(14a-14e) and marker 42 provided outside the effective image area can be detected by an image sensor. Here, in case of selecting an abstract mode, expanding copying is prohibited, and when the magnification is already set, an operation to return the magnification to a nonmagnified ratio compulsorily is performed. In such a way, it is possible to perform the detection of the position of the designation levers (14a-14e) by the image sensor surely, and to perform designated column jumping edit in case of setting a mode at the abstract mode.

Title: Semiconductor device and lead frame used for assembling the same
Inventor: ENOMOTO USUKE
IPC: H01L23/48
Filed: 1982-02-15
Abstract: PURPOSE:To improve the thermal fatigue lifetime of a semiconductor device by mounting circuit elements through solder containing a range of 95-99.5% of lead. CONSTITUTION:A copper plate is plated with Ni 14, and solder plating 15 is superposed. A solder plating film 15 has a lower layer of lead 16 and an upper layer of tin 17, and when both are molten to form a solder, the thickness of lead 16 is higher than 95% and lower than approx. 99.5% by weight. The thicknesses of the respective layers are accurately controlled by plating, thereby readily obtain the solder of the prescribed component ratio. In order to prevent the oxidation of the lead 16 with the tin 17 which can be hardly oxidized as an upper layer, the tin layer 17 should be at least higher than approx. 0.2mum, and in case of 0.2mu, when the layer 16 is formed in 21mum, the lead contents arrive at 99.4%. When a pellet is bonded through a solder plating layer with this structure, the lead content reaches extremely high, and thermal fatigue lifetime is extended, and since tin is covered, it is not oxidized, and when the pellet is bonded, an oxide does not impregnate into the solder bonding layer, thereby inhibiting the increase in the thermal resistance.

Filed: 1979-02-26
Abstract: PURPOSE: To most effectively pick out a turning force from blades and efficiently obtain motive power, by providing the blades so that they rotate half while they revolve once around a main rotary shaft.  
     CONSTITUTION: When the rotary frame E of a windmill rotates, blade gears C 1 , C 2 , C 3 , C 4  and blades D 1 , D 2 , D 3 , D 4  revolve around a main rotary shaft Y. Since the blade gears C 1 , C 2 , C 3 , C 4  are engaged with planet gears B 1 , B 2 , B 3 , B 4  engaged with a wind direction gear A, the blades D 1 , D 2 , D 3 , D 4  rotate half while the rotary frame E rotates once. The blades D 1 , D 3  receive revolving thrusts from a wind. The blade D 2  receives the wind pressure on the entire surface of the blade. The blade D 4  suffers from the lowest resistance. As a result, the most effective turning force is caused by the blades to rotate the windmill to transmit motive power to an electricity generator J.
